Parentage is the term for a court proceeding that determines the identity of a child's parents, and their respective rights and responsibilities of each parent. Only a skilled attorney can advise you regarding when to initiate a parentage action, what happens if you do not, and how to most effectively participate once a case has been filed.  If you are the parent of a child regarding whom there is no court order establishing parentage, you need an experienced attorney to guide you thorought the process.
